Fields
In the response body you will find several fields describing the error.
status
The HTTP status code.
title

type

This URI is not necessarily resolvable, it's main purpose is to identify the problem type, but it sometimes can give you additional information on the problem. It can also be set to about:blank when the problem has no additional semantics beyond that of the HTTP status code.
detail
